Math.random

When generating a random number between bottomNumber and topNumber would it also be possible to write the code as follows?

Math.floor( Math.random() * (topNumber-bottomNumber + 1 + bottomNumber));

Just wondering if Javascript will also allow for everything to be kept within parentheses?

JavaScript will allow you to use parentheses like that, however, with the JS you have written you will get a number between 0 and topNumber.

Since you have added and subtracted bottomNumber in that expression, it is cancelled out and has no impact on the sum.
